Hi all, Silly question. I've just thrown together an OpenNebula cluster for evaluation purposes and have it using a back-end Ceph cluster for storage.
Image creation works, but one thing I observe is that the VMs sit in the PROLOG stage for a long time. During this process, I see an rbd process busily copying the image to a temporary rbd for the instance. The call specifically is a 'rbd copy' command. I see in the manual pages for rbd: > clone [parent-snapname] [image-name] > Will create a clone (copy-on-write child) of the parent > snapshot. Object order will be identical to > that of the parent image unless specified. Size will be the > same as the parent snapshot. Surely this would be more efficient than creating copies of the images. Is there a reason why 'copy' was chosen rather than 'clone' in OpenNebula? -- Stuart Longland Systems Engineer _ ___ \ /|_) | T: +61 7 3535 9619 \/ | \ | 38b Douglas Street F: +61 7 3535 9699 SYSTEMS Milton QLD 4064 http://www.vrt.com.au _______________________________________________ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
